It should be noted that, when an element is expressed as “fixed on” another element, the element may be directly on the another element, or one or more middle elements may exist between the another element. When one element is expressed as “electrically connected to” another element, the element may be directly connected to the another element, or one or more middle elements may exist between the another element. Orientation or position relationships indicated by the terms “upper”, “lower”, “inner”, “outer”, and “bottom” used in this specification are based on the orientation or position relationships shown in the accompanying drawings, only to help describe the present invention and simplify the description, instead of indicating or implying that the mentioned device or element needs to have a specific orientation, and is constructed and operated in the specific orientation. Therefore, it should not be understood as a limitation to the present invention. In addition, the terms “first”, “second”, “third”, and “fourth” are only used to describe the purpose, instead of being understood as indicating or implying the relative importance.

Unless defined otherwise, all technical and scientific terms used in this specification are the same as the meanings generally understood by a person skilled in the technical field of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific implementations, instead of being used to limit the present invention. The term “and/or” used in this specification includes any and all combinations of one or more related listed items.

In addition, the technical features involved in the following described different embodiments of the present invention may be combined with each other provided that they do not conflict with each other.

Referring to FIG. 1 , an embodiment of the present invention provides a remote control 400, configured to remotely control a movable object. The movable object may be an unmanned aerial vehicle (UAV), a model airplane, an electronic toy, or the like. The remote control 400 includes a first rocker device 100, a second rocker device 200, and a body 402, and both the first rocker device 100 and the second rocker device 200 are installed on the body 402.

A first joystick component of the first rocker device 100 is configured to move in parallel relative to the body 402, to trigger the remote control 400 to generate a corresponding remote control instruction. Specifically:

when the first joystick component moves in parallel relative to the body 402, the processor 410 generates a remote control instruction, where the remote control instruction is used to control the movable object to move in a horizontal plane of the movable object.

In some embodiments, when the first joystick component of the first rocker device 100 moves in parallel relative to the body 402 along a positive direction of a first axis (the X axis in FIG. 1 ), the movable object is controlled to move to the right side in the horizontal plane;

when the first joystick component of the first rocker device 100 moves in parallel relative to the body 402 along a negative direction of the first axis, the movable object is controlled to move to the left side in the horizontal plane;

when the first joystick component 20 of the first rocker device 100 moves in parallel relative to the body 402 along a positive direction of a second axis (the Y axis in FIG. 1 ), the movable object is controlled to move to the front side in the horizontal plane; and when the first joystick component of the first rocker device 100 moves in parallel relative to the body 402 along a negative direction of the second axis, the movable object is controlled to move to the back side in the horizontal plane.

The second joystick component of the second rocker device 200 is configured to move straightly relative to the body 402 along a first direction (that is, the X′ direction in FIG. 31 ) or a second direction (that is, the Y′ direction in FIG. 33 ), and is further configured to rotate along a clockwise direction or an anticlockwise direction, to trigger the remote control 400 to generate a corresponding remote control instruction. Obviously, the first direction is opposite to the second direction. Specifically:

when the second joystick component of the second rocker device 200 moves straightly relative to the body 402 along the first direction, the movable object is controlled to move upward in a vertical direction;

when the second joystick component of the second rocker device 200 moves straightly relative to the body 402 along the second direction, the movable object is controlled to move downward in the vertical direction;

when the second joystick component of the second rocker device 200 rotates relative to the body 402 along a clockwise direction, the movable object is controlled to rotate in a horizontal plane along a clockwise direction; and

when the second joystick component of the second rocker device 200 rotates relative to the body 402 along an anticlockwise direction, the movable object is controlled to rotate in the horizontal plane along an anticlockwise direction.

Referring to FIG. 2 , the remote control 400 further includes a processor 410 and a signal transmission device 420.

The processor 410 is connected to the first rocker device 100 and the second rocker device 200, and is configured to generate, according to parallel moving of the first joystick component of the first rocker device 100 relative to the body 402 and parallel moving, swinging, rotating, or moving straightly of the second joystick component of the second rocker device 200 relative to the body 402, a remote control instruction used to control the movable object to move correspondingly. The processor 410 may be a general processor, a digital signal processor (DSP), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA), a single chip microcomputer, an ARM (Acorn RISC Machine), or another programmable logic device, a discrete gate or a transistor logic, a discrete hardware component, or any combination of these components.

The signal transmission device 420 is connected to the processor 410, and is configured to receive a remote control instruction generated by the processor 410, and send the remote control instruction to the remotely controlled movable object.

In this embodiment of the present invention, the first rocker device 100 is used by a right hand of a user to operate, and the second rocker device 200 is used by a left hand of a user to operate. It may be understood that, in some other embodiments, positions of the first rocker device 100 and the second rocker device 200 may be exchanged according to using habits of a user.

In addition, it should be noted that, a “swing” rocker device is used on a conventional remote control. The “swing” means that when the rocker device is being controlled, a joystick component of the rocker device generates, by swinging relative to a point on a rod body of the joystick component, a remote control instruction used to control a remotely controlled movable object to move correspondingly. Relative to a conventional “swing” rocker device, the first rocker device 100 and the second rocker device 200 in the embodiments of the present invention discard the conventional “swing” form, and use a new control (or “parallel movement”) form, or a “straight movement” form, or a “rotating” (that is, spinning) form. It should be understood that, when the solutions of the present invention are implemented, the first rocker device 100 and the second rocker device 200 do not need to be used at the same time, but may be used independently. That is, it is unnecessary to use the first rocker device 100 and the second rocker device 200 with the new construction on one remote control at the same time. Instead, the first rocker device 100 or the second rocker device 200 may be combined with the conventional “swing” rocker device, and used on one remote control. That is, the first rocker device 100 in the embodiments of the present invention may be used on a left/right rocker device of the remote control, and the conventional “swing” rocker device may be used on a right/left rocker device; or the second rocker device 200 in the embodiments of the present invention may be used on a left/right rocker device of the remote control, and the conventional “swing” rocker device may be used on a right/left rocker device.

Referring to FIG. 3 to FIG. 5 , the first rocker device 100 includes a first shell 10, a first joystick component 20, a first restoring component 30, a second restoring component 40, a fixing piece 50, a first magnetic element 60, and a first circuit board 70.

The first joystick component 20 is partially accommodated in the first shell 10, and the first restoring component 30, the second restoring component 40, the fixing piece 50, the first magnetic element 60, and the first circuit board 70 are accommodated in the first shell 10.

One end of the first joystick component 20 is connected to the first magnetic element 60 by using the fixing piece 50, the first joystick component 20 may move in parallel relative to the first shell 10 or the body 402, and the first magnetic element 60 may be driven from an initial position by the first joystick component 20 to move in parallel relative to the first circuit board 70 in a plane. The first circuit board 70 is parallel to the plane, and the first joystick component 20 and the plane intersect.

The “initial position” of the first joystick component 20 in the embodiments of the present invention refers to an original position in a natural state in which the first joystick component 20 is not touched by a user. In a general case, when the first joystick component 20 is in the initial position, a central axis of a first rod body of the first joystick component 20 and a central axis of the first rocker device 100 overlap. The “initial position” of the first magnetic element 60 also refers to an original position of the first magnetic element 60 in a natural state in which the first joystick component 20 is not touched by a user. In a general case, when the first magnetic element 60 is at a central position, a central point penetrates the central axis of the first rocker device 100.

The “parallel movement” in the embodiments of the present invention means that all points on one component move by a same distance according to a direction, and the component does not rotate relative to any point on the component. When the first joystick component 20 moves in parallel relative to the first shell 10 and the body 402, any two points on the first joystick component 20 move in a same direction and move by a same distance, and the first joystick component 20 does not rotate.

The first restoring component 30 and the second restoring component 40 may generate a composite force that restores the first joystick component 20, so that the first magnetic element 60 is restored to the initial position. When neither the first restoring component 30 nor the second restoring component 40 generates an acting force for the first joystick component 20, the first joystick component 20 and the first magnetic element 60 are separately at the initial position.

The first shell 10 is fixedly installed on the body 402 by using screws. The first shell 10 includes a first shell portion 11 and a second shell portion 12, the first shell portion 11 is installed on the second shell portion 12, and a first cavity 13 is formed between the first shell portion 11 and the second shell portion 12. The first shell portion 11 and the second shell portion 12 separately include a bottom wall, and a side wall extending from an outer edge of the bottom wall. The bottom wall and the side wall of the first shell portion 11 and the second shell portion 12 are enclosed to form the first cavity 13.

Referring to both FIG. 6 and FIG. 7 , the first shell portion 11 includes a circular limiting portion 112 and a first installation column 116, the circular limiting portion 112 is disposed on a bottom wall of the first shell portion 11, and multiple first installation columns 116 are extended from the bottom wall of the first shell portion 11. The bottom wall of the first shell portion 11 is provided with a first through hole 110, and a central line of the circular limiting portion 112 and a central line of the first through hole 110 overlap. The first through hole 110 is a reserved moving space for the first joystick component 20 to move in parallel relative to the first shell 10 and the body 402.

The second shell portion 12 includes a location column 124 and a second installation column 126, two location columns 124 are disposed on a bottom wall of the second shell portion 12, and multiple second installation columns 126 are extended from the bottom wall of the first shell portion 11. The quantity of the second installation columns 126 is equal to the quantity of the first installation columns 116, and the position of each of the second installation columns 126 corresponds to the position of a corresponding first installation column 116.

The first joystick component 20 includes an operating handle 21 and a joystick 22. The joystick 22 includes a first rod body 220 and a round sliding portion 222. The first rod body 220 is a cylinder, the round sliding portion 222 is sleeved and fixed on the first rod body 220, one end of the first rod body 220 is fixedly connected to the operating handle 21, and the other end of the first rod body 220 is fixedly connected to the fixing piece 50. In this embodiment, the operating handle 21 and the joystick 22 are separate elements. It may be understood that, in some other embodiments, the operating handle 21 and the joystick 22 may be an integral structure.

The first restoring component 30 includes a first active block 31, a first elastic element 32, and a first installation seat 33.

The quantity of the first active block 31 is two, and each first active block 31 is roughly rectangular and includes a first fixing portion 314.

The quantity of the first elastic elements 32 is two. In this embodiment, the first elastic element 32 is a pressure spring. It may be understood that, in some other embodiments, the first elastic element 32 may be another elastic element that may provide a restoring force.

The first installation seat 33 is a shell, and is provided with a second through hole 330 and a first accommodating groove 333. The second through hole 330 is in communication with the first accommodating groove 333. The second through hole 330 is located at a central part of the bottom wall of the first installation seat 33. Two relative sides of the inner side wall of the first accommodating groove 333 are separately disposed with a second fixing portion 334, and the other two relative sides of the inner side wall of the first accommodating groove 333 are separately disposed with a first limiting column 335.

The two first active blocks 31 are installed on the first accommodating groove 333, and are disposed along the first axis. The two first limiting columns 335 are disposed between the two first active blocks 31, and the two first active blocks 31 are spaced with a preset distance. One end of either of the first elastic elements 32 is installed on a second fixing portion 334 of the first installation seat 33, and the other end of either of the first elastic element 32 is installed on a first fixing portion 314 of the first active block 31, so that each first elastic element 32 is compressed between a first active block 31 and the first installation seat 33.

The fixing piece 50 is provided with an accommodating hole 502, and the first magnetic element 60 is accommodated and fixed in the accommodating hole 502. In this embodiment, the fixing piece 50 is a fixing nut.

The first circuit board 70 includes a first magnetic sensor 702, and the first magnetic sensor 702 is faced to the first magnetic element 60. When the first magnetic element 60 is at the initial position, the first magnetic sensor 702 is aligned with the first magnetic element 60. Two relative sides of the first circuit board 70 are separately provided with a location hole 704. In this embodiment, the first magnetic sensor 702 is a Hall element. It may be understood that, in some other embodiments, the first magnetic sensor 702 may be another element that may sense the magnetic field change, for example, a magnetic encoder.

When the first rocker device 100 is being assembled, the joystick 22 penetrates the first through hole 110, and the operating handle 21 is fixedly installed on one end of the joystick 22. The joystick 22 successively penetrates the second through hole 330 and the third through hole 430, and the other end of the joystick 22 is fixedly installed on the fixing piece 50. The two first active blocks 31 are separately disposed on two relative sides of the joystick 22, and the two second active blocks 41 are separately disposed on the other two relative sides of the joystick 22.

The first circuit board 70 is fixedly installed on the bottom wall of the second shell portion 12, and the two location columns 124 are correspondingly accommodated in the location hole 704.

The first restoring component 30 and the second restoring component 40 are placed in the first shell portion 11, and the second shell portion 12 covers the first shell portion 11, so that the first magnetic element 702 is faced to the first magnetic element 60, the second installation column 126 is abutted against the second installation seat 43, and the first installation seat 33 and the second installation seat 43 are clamped between the second installation column 126 and the first shell portion 11. The first installation column 116 is aligned with the second installation column 126 and the third installation column 436.

After successively penetrating the second installation column 126 and the third installation column 436, multiple screws are inserted and fixed in the first installation column 116, the second shell portion 12, the second installation seat 43, the first installation seat 33, and the first shell portion 11 are fixed together, and the round sliding block 222 is accommodated in a gap between the first installation seat 33 and the first shell portion 11.

When being used, referring to FIG. 8 and FIG. 9 , the first joystick component 20 may be pushed to move in parallel relative to the first shell 10 and the body 402 along the first axis, and one of the first active blocks is pushed by the first rod body 220, so that the first elastic element 32 connected to the pushed first active block 31 is compressed. The first magnetic element 60 is driven from the initial position to move in the plane along the first axis. The first magnetic sensor 702 senses the magnetic field change of the first magnetic element 60, and obtains a moving position of the first magnetic element 60 along the first axis. The processor 410 generates a remote control instruction according to the moving position of the first magnetic element 60 obtained by the first magnetic sensor 702, and the remote control 400 sends the remote control instruction to the remotely controlled movable object, so that the movable object moves in a horizontal plane of the movable object along a direction corresponding to the direction in which the first joystick component 20 moves in parallel.

When the first rod body 220 is abutted against an inner wall of the first through hole 110 and the second installation seat 43, and the round sliding portion 222 is abutted against the circular limiting portion 112, the first joystick component 20 stops moving in parallel along the first axis. It may be understood that, in some other embodiments, according to an actual requirement, only the inner wall of the first through hole 110 or the second installation seat 43 may be selected to be abutted against the first rod body 220, or only the round sliding portion 222 may be selected to be abutted against the circular limiting portion 112, so that the first joystick component 20 stops moving in parallel along the first axis.

After the force that pushes the first joystick component 20 disappears, the compressed first elastic element 32 restores to the original shape, to push the first active block 31 to move along the first axis, so that the first joystick component 20 drives the first magnetic element 60 to restore to the initial position.

Similarly, referring to FIG. 10 and FIG. 11 , the first joystick component 20 may be pushed to move in parallel relative to the first shell 10 and the body 402 along the second axis, and one of the second active blocks 41 is pushed by the first rod body 220, so that the second elastic element 42 connected to the pushed second active block 41 is compressed.

The first magnetic element 60 is driven from the initial position to move in the plane along the second axis. The first magnetic sensor 702 senses the magnetic field change of the first magnetic element 60, and obtains a moving position of the first magnetic element 60 along the second axis. The processor 410 generates a remote control instruction according to the moving position of the first magnetic element 60 obtained by the first magnetic sensor 702, and the remote control 400 sends the remote control instruction to the remotely controlled movable object, so that the movable object moves in a horizontal plane of the movable object along a direction corresponding to the direction in which the first joystick component 20 moves in parallel.

When the first rod body 220 is abutted against the inner wall of the first through hole 110 and the first installation seat 33, and the round sliding portion 222 is abutted against the circular limiting portion 112, the first joystick component 20 stops moving along the second axis. It may be understood that, in some other embodiments, according to an actual requirements, only the inner wall of the first through hole 110 or the first installation seat 33 may be selected to be abutted against the first rod body 220, or only the round sliding portion 222 may be selected to be abutted against the circular limiting portion 112, so that the first joystick component 20 stops moving in parallel along the second axis.

After the force that pushes the first joystick component 20 disappears, the compressed second elastic element 42 restores to the original shape, to push the second active block 41 to move along the second axis, so that the first joystick component 20 drives the first magnetic element 60 to restore to the initial position.

It may be understood that, when the first joystick component 20 moves in parallel relative to the first shell 10 and the body 402 along any direction, the first restoring component 30 and the second restoring component 40 may generate a composite force to restore the first joystick component 20, so that the first joystick component 20 and the first magnetic element 60 on the first joystick component 20 are restored to the initial position. That is, when an external force applied to the first joystick component 20 disappears, the first restoring component 30 and the second restoring component 40 collaborate and cooperate to restore the first joystick component 20 to the initial position.

It should be understood that, the “collaborate” may be understood as including the following two situations.

Situation 1: The first restoring component 30 and the second restoring component 40 separately generate a force used to restore the first joystick component 20, and a composite force of the two forces generated by the first restoring component 30 and the second restoring component 40 restores the first joystick component 20 to the initial position. For example, when the first joystick component 20 moves in parallel relative to the first shell 10 and the body 402 along any other direction except the first axis and the second axis, because the first joystick component 20 displaces relative to the directions of the first axis and the second axis, composite force of the forces generated by the first restoring component 30 and the second restoring component 40 restores the first joystick component 20, so that the first joystick component 20 and the first magnetic element 60 are restored to the initial position.

Situation 2: Only one of the first restoring component 30 and the second restoring component 40 generates a force used to restore the first joystick component 20, and the force restores the first joystick component 20 to the initial position. For example, when the first joystick component 20 only moves in parallel relative to the first shell 10 and the body 402 along the direction of the first axis, because the first joystick component 20 displaces relative to the direction of the first axis, but does not displace relative to the direction of the second axis, only the first restoring component 30 generates a force that restores the first joystick component 20, so that the first joystick component 20 and the first magnetic element 60 are restored to the initial position, but the second restoring component 40 does not generate a force that restores the first joystick component 20. Likewise, when the first joystick component 20 only moves in parallel relative to the first shell 10 and the body 402 along the direction of the second axis, because the first joystick component 20 displaces relative to the direction of the second axis, but does not shift relative to the direction of the first axis, only the second restoring component 40 generates a force that restores the first joystick component 20, so that the first joystick component 20 and the first magnetic element 60 are restored to the initial position, but the first restoring component 30 does not generate a force that restores the first joystick component 20.

When the first magnetic element 60 is driven from the initial position by the first joystick component 20 to move relative to the first magnetic sensor 702 in the plane along any direction, the first magnetic sensor 702 senses the magnetic field change of the first magnetic element 60, and obtains a moving position of the first magnetic element 60 along any direction in the plane. The processor 410 generates a remote control instruction according to the moving position of the first magnetic element 60 obtained by the first magnetic sensor 702, and the remote control 400 sends the remote control instruction to the remotely controlled movable object, so that the movable object moves in the horizontal plane along a direction corresponding to the direction in which the first magnetic element 60 moves in parallel.

In the first rocker device 100 of the embodiments of the present invention, the first magnetic element 60 is driven from the initial position by the first joystick component 20 to move in parallel relative to the first magnetic sensor 702 along any direction in the plane, the first restoring component 30 and the second restoring component 40 may generate a composite force to restore the first joystick component 20, so that the first magnetic element 60 is restored to the initial position, to simplify the operation. In addition, the parallel moving direction of the first joystick component 20 may correspond to the moving direction of the remotely controlled movable object, so that the operation of the first rocker device 100 is intuitive, simple, and easy for a user to memorize.

The second joystick component of the second rocker device 200 can move relative to the body 402, to trigger the remote control 400 to generate a remote control instruction. The moving includes swinging, rotating, and moving in parallel. For example, the second rocker device 200 may use a swing structure in the prior art to trigger the remote control 400 to generate a first remote control instruction when the second joystick component of the second rocker device 200 swings along a first direction (such as swinging forward relative to a user); trigger the remote control 400 to generate a second remote control instruction when the second joystick component of the second rocker device 200 swings along a second direction (such as swinging backward relative to the user); trigger the remote control 400 to generate a third remote control instruction when the second joystick component of the second rocker device 200 swings along a third direction (such as swinging to the left relative to the user); and trigger the remote control 400 to generate a fourth remote control instruction when the second joystick component of the second rocker device 200 swings along a fourth direction (such as swinging to the right relative to the user).

For another example, the second joystick component of the second rocker device 200 may move in parallel along a central axis and in a direction away from the first magnetic sensor 702, to trigger the remote control 400 to generate a first remote control instruction; the second joystick component of the second rocker device 200 may move in parallel along a central axis and in a direction close to the first magnetic sensor 702, to trigger the remote control 400 to generate a second remote control instruction; and the second joystick component of the second rocker device 200 may rotate clockwise or anticlockwise around a central axis, to trigger the remote control 400 to generate a third remote control instruction or a fourth remote control instruction.

The first remote control instruction, the second remote control instruction, the third remote control instruction, and the fourth remote control instruction may control the movable object to perform any one of the following movements: controlling the movable object to move upward in a vertical direction, controlling the movable object to move downward in a vertical direction, controlling the movable object to rotate along a clockwise direction in a horizontal plane of the movable object, and controlling the movable object to rotate along an anticlockwise direction in a horizontal plane of the movable object.

Referring to FIG. 33 , a pushing force is applied to the second rod body 210′, so that when the hinge pin 214′ moves straightly from the initial position along the second direction (for example, the downward direction represented by Y′ in FIG. 33 ) together with the second rod body 210′, the third limiting column 2204′ is abutted against one of the abutting portions 2222′, the hinge pin 214′ drives another abutting portion 2222′ to open along the second direction, and the third elastic element 224′ is stretched.

When the pushing force applied to the second rod body 210′ disappears, the stretched third elastic element 224′ restores to the original shape, to pull the opened swing block 222′ to restore, to drive the hinge pin 214′, the second rod body 210′, and the second magnetic element 23′ to restore, so that the second magnetic element 23′ moves to the initial position along the first direction.

Referring to FIG. 34 and FIG. 35 , a torsion is applied to the second rod body 210′, so that the second rod body 210′ drives the third rod body 212′, the third restoring component 22′, and the second circuit board 24′ to rotate along the clockwise direction or the anticlockwise direction, and the connection end 2126′ drives the rotation piece 251′ and the fixing piece 253′ to rotate relative to the connection frame 250′ and the third circuit board 27′ along the clockwise direction or the anticlockwise direction.

When the fixing piece 253′ rotates relative to the third circuit board 27′ along the clockwise direction or the anticlockwise direction, the third magnetic element 26′ rotates from the initial position relative to the third magnetic sensor 272′ along the clockwise direction or the anticlockwise direction. The third magnetic sensor 272′ senses the magnetic field change of the third magnetic element 26′, and obtains a rotation amount of the third magnetic element 23 along the clockwise direction or the anticlockwise direction.

Referring to FIG. 36 , the structure of the second rocker device 300 provided by another embodiment of the present invention is basically the same as the structure of the second rocker device 200 of the foregoing embodiments, and the difference is: the second rocker device 300 replaces the magnetic sensor 272 of the second rocker device 200 with a potentiometer 274′.

The potentiometer 274′ is disposed on the circuit board 27′. The connection end 2126′ is inserted into the potentiometer 274′, and in contact with the potentiometer 274′. The potentiometer 274′ includes a resistor body, and the connection end 2126′ includes an electric brush.

When the connection end 2126′ rotates relative to the potentiometer 274′ and the third circuit board 27′ along the clockwise direction or the anticlockwise direction, the potentiometer 274′ obtains a rotation amount of the connection end 2126′ along the clockwise direction or the anticlockwise direction according to a resistance or voltage change. The circuit board 27′ generates a corresponding remote control instruction, and the remote control 400 sends the remote control instruction to the controlled movable object, so that the movable object rotates in the horizontal plane of the movable object along the clockwise direction or the anticlockwise direction.

The second rocker device 300 may replace the second rocker device 200 provided in the foregoing embodiments, and is installed on the body 402.

In the second rocker devices 200 and 300 of the embodiments, the second rod body 210′ only has actions in four directions: moving straightly along a first direction and a second direction, and rotating along a clockwise direction and an anticlockwise direction. The movable object separately controlled to perform a vertical upward movement (that is, an ascending movement), a vertical downward movement (that is, a descending movement), a clockwise rotation movement (that is, rotating to the right), and an anticlockwise rotation movement (that is, rotating to the left). The operation actions of a user for the second rocker device are just in a one-to-one correspondence with the movement actions of the movable object, so that the operation of the remote control is more simple and understandable, and easy for the user to memorize. In addition, when the force applied to the second rod body 210′ disappears, the third restoring component 22′ or the fourth restoring component 25′ may restore the second rod body 210′, to further simplify the operation of the second rocker device 200.

In some embodiments, the movable object is an unmanned aerial vehicle, and the remote control 400 is configured to control the unmanned aerial vehicle. When the first joystick component 20 of the first rocker device 100 moves in parallel relative to the first shell 10 along the first axis, for example, when the first joystick component 20 moves forward in parallel or move backward in parallel relative to the user, the remote control 400 remotely controls the unmanned aerial vehicle to move forward or move backward relative to the user, that is, fly forward or fly backward in a plane of the unmanned aerial vehicle. When the first joystick component 20 moves in parallel along any direction, for example, when the first joystick component 20 moves in parallel to the front right side relative to the user, the remote control 400 remotely controls the unmanned aerial vehicle to move to the front right side relative to the user, that is, fly to the front right direction in a plane of the unmanned aerial vehicle. The movement direction of the first joystick component 20 is in a one-to-one correspondence with the movement direction in the plane of the unmanned aerial vehicle, so that the operation of the remote control 400 is intuitive and simple. The first restoring component 30 and the second restoring component 40 may generate a composite force to restore the first joystick component 20, so that the first magnetic element 60 is restored to the initial position, to simplify the operation of the remote control device 400.

When the second rod body 210′ of the second rocker devices 200 and 300 moves straightly along the first direction (for example, the upward direction in FIG. 31 ), the remote control 400 controls the unmanned aerial vehicle to ascend; and when the second rod body 210′ moves straightly along the second direction (for example, the downward direction in FIG. 33 ), the remote control 400 controls the unmanned aerial vehicle to descend. When the second rod body 210′ rotates along the clockwise direction or the anticlockwise direction, the remote control 400 controls the unmanned aerial vehicle to rotate to the right or rotate to the left.

The movement directions of the second rod body 210′ are in a one-to-one correspondence with the movement directions of the unmanned aerial vehicle in the vertical direction and the horizontal plane, so that the operation of the remote control 400 is intuitive and simple. The second rod body 210′ only has actions of four directions, and this is easy for the user to memorize. In addition, when the force applied to the second rod body 210′ disappears, the third restoring component 22′ or the fourth restoring component 25′ may restore the second rod body 210′, to further simplify the operation of the remote control device 400.

Because the operation of the remote control 400 in the embodiments of the present invention and the first rocker device 100 and/or the second rocker devices 200 and 300 used by the remote control 400 is simple, intuitive, and easy to memorize, a faulty operation on the movable object caused by a user unfamiliar with the operation can be effectively avoided, for example, a bombing phenomenon caused by a faulty operation on an unmanned aerial vehicle can be avoided.
